Here I am explain how to show alert message
in Asp.Net from code behind
using C#.
Source Code :
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>show alert message in asp.net from code behind
Asp.NetJitendra</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="btnClick"
Text="Click"
runat="server"
OnClick="btnClick_Click"
/>
</div>
</form>
</body>
</html>
Code Behind :
Source 1:-
protected void
btnClick_Click(object sender, EventArgs e)
{
ClientScript.RegisterStartupScript(this.GetType(),
"alertmsg", "alert('This alert msg from code behind');",
true);
}
Source 2:-
protected void
btnClick_Click(object sender, EventArgs e)
{
Messagebox("This alert msg from code
behind");
}
private void Messagebox(string Message)
{
Label lblMessageBox = new
Label();
lblMessageBox.Text =
"<script language='javascript'>" +
Environment.NewLine +
"window.alert('" + Message + "')</script>";
Page.Controls.Add(lblMessageBox);
}
